, poor access to medical home was found to significantly increase risk of hospital readmission by 56% compared with those with highest level of access after adjusting for covariates (Auger et al., 2013). However, a total score of medical home quality represented by Parent's Perception of Primary Care (P3C) and other five subscale scores such as continuity, contextual knowledge, comprehensiveness, communication, and coor- dination were not associated with readmission. In addition Moncrief et al. (2014) recently explored the relationship between single parent households and ER reutilization and hospital readmission. Patients in single parent households were significantly (44%) more likely to reutilize ED or be readmitted within 12 months than those in married parent households. When adjusted for income, the relationship between single parent households and readmission became non-significant. It could be concluded that higher ER reutilization and hospital readmission rates by single parent household were primarily related to household income among four assessed psychological variables, including household income, caregiver risk of psychological distress, ratio of in-home children to adults, and regular attendance at childcare or a secondary home.
